Answer: (B)

Identifying the patient is crucial before collecting a blood sample. This step ensures that the right sample is taken from the correct individual, which is vital for accurate diagnosis and treatment. Proper patient identification helps to avoid mix-ups that could lead to administering wrong treatments or interfacing erroneous medical records.

Beginning the procedure with patient identification allows the phlebotomist to confirm that they are working with the correct individual and that all paperwork is aligned with the patient’s identity. This step establishes a clear connection between the patient and the lab results that will be generated from the blood sample, ensuring that necessary precautions are taken to maintain patient safety and integrity of the testing process.
